Internal combustion engine
Answer:
Squats involve flexion (forward motion) and extension (backward on the way up), so would fit into the sagittal plane. Frontal plane motion would include leaning from left to right as in sidebends and lateral raises, or perhaps you might picture jumping jacks for a good image of movement along the frontal plane.
Acceleration will always be samei.e.
Acceleration=g= 9.81 m/s^2
Answer:
<em>Force B</em>
Explanation:
<u>Friction Force
</u>
It's a force that appears when an object is tried to move on a rough surface. There are two cases: when the object is at rest, we have the friction static coefficient and when the object is already moving, we have the dynamic coefficient. The static coefficient is usually greater than the second because it's harder to overcome the friction when the object is at rest.
We are told that John pushes the bed to the left with enough force to overcome the force of friction. If the movement is intended to be to the left side, the friction force appears to the right, since it always opposes to the movement. Thus the force B is the one who represents the friction force in this situation
Answer:
a= F/m
Explanation:
Newton's Second Law of Motion : It states that that the rate of change of momentum of a body is proportional to the applied force and it takes place on the direction of the force applied.
Mathematically,
F = m ( v-u)/t
F = ma
a = F/m
The same force was applied to each of the balls yet, the acceleration of one was greater than the other. The kickball accelerated at a greater pace than the soccer ball because it has a lesser mass hence the effect or impact of the force applied will be greatly felt by the kickball.
